Abstract

Objectives: The goals of the study are to determine whether or not there is a correlation between the QT interval and IMVP, to provide an explanation for sudden cardiac death in some cases, and to show how IMVP symptoms are linked to certain arrhythmias.

Methods: QTC intervals were measured in 43 patients with idiopathic mitral valve prolapse (11 men and 32 women with mean age 46±17 years). All patients underwent a clinical and echocardiographic examination, and ECG taking to assess the incidence of long QT in patients with IMVP.

Results: The data show that 36 of the 43 patients with IMVP have a prolonged QT interval, while only 2 of the 38 patients in the control group have. There was also an uptick in arrhythmia cases when the QT interval was prolonged.

Conclusion: Individuals with IMVP have an increased risk of arrhythmias, and this risk is even greater in patients with very long QT, which can cause life-threatening ventricular arrhythmias, as shown by this study.
